We propose an algebraic method of extracting excited states from lattice correlation functions which is also useful to lattice gauge theorists in general, as well as data analysts investigating exponentially decaying signals. Instead of fitting to a linear combination of exponentials, we adopt a variant of Prony’s method to obtain M energies (exponential decay rates) by finding the roots of an Mth order polynomial. I will describe the challenges faced in this approach and demonstrate our attempts to overcome them.</span></div><div dir="auto" style="font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small;" class=""><span style="font-family: Calibri, Helvetica, sans-serif; font-size: 11pt;" class=""><br class=""></span></div><div dir="auto" style="font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small;" class=""><span style="font-family: Calibri, Helvetica, sans-serif; font-size: 11pt;" class=""><span class="">BlueJeans connection:<span style="color: rgb(0, 111, 201);" class=""> <a href="https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbluejeans.com%2F321085255&data=02%7C01%7Csufian%40jlab.org%7Cc8be43dd0ab5441ee29408d6a97e98a5%7Cb4d7ee1f4fb34f0690372b5b522042ab%7C1%7C0%7C636882758528685933&sdata=0vwu20yt5d5ydFsYJVWC0enSWx0zu0KEf7uycMANj3w%3D&reserved=0" originalsrc="https://bluejeans.com/321085255" shash="BkYxMRkEDJ3D2TEaE0tiEP2KEQNv4AF5MfF6fKJOuVTrKMp9FLjRT5Y/GsB9ezf3DeW1jxhK/1Eo/jdlPUMvWNM8+YnNcoJXN0xp/0WzqDorrlLPDvMa3DQcFAzlILNQ93ZRKpL56Rqx649D57WSME0vBalWq2SqwwGVChTH0qI=" class="OWAAutoLink" id="LPlnk34838" previewremoved="true">https://bluejeans.com/321085255</a><br class=""></span></span><br class="">Raza, Vincent, Carlota</span></div><br class="Apple-interchange-newline"></span></span></span></div></blockquote></div><br class=""></div></body></html>
